COVID‐19 and asthma, the good or the bad?


"In summary, we have seen a new zoonotic coronavirus, SARS‐CoV‐2, infection that has had a devastating effect on the host immunity via the inhibition of interferons leading to aberrant innate immune response, macrophage inflammation in releasing a cytokine storm and exhaustion of the cellular immunity of T lymphocytes.9 Fortunately, due to chronic and sustained type 2 immune inflammation in the lungs of asthmatic patients, or by the medications they use for asthma control, it seems asthma may not be a major confounding disease in COVID‐19 infection, and this unexpected phenomenon may shed a new light on finding therapies or preventative strategies for SARS‐CoV‐2."

COVID‐19: A series of important recent clinical and laboratory reports in immunology and pathogenesis of SARS‐CoV‐2 infection and care of allergy patients


"The “coronavirus disease 2019 (COVID‐19)” outbreak was first reported in December 2019 (China). Since then, this disease has rapidly spread across the globe and in March 2020 the World Health Organization (WHO) declared the COVID‐19 pandemic.1 Since the outbreak was first announced, our journal has extensively focused on the clinical features, outcomes, diagnosis, immunology, and pathogenesis of COVID‐19 and its infectious agent severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2).."

Immunology of COVID‐19: mechanisms, clinical outcome, diagnostics and perspectives – a report of the European Academy of Allergy and Clinical Immunology (EAACI)


"We also summarize known and potential SARS‐CoV‐2 receptors on epithelial barriers, immune cells, endothelium and clinically involved organs such as lung, gut, kidney, cardiovascular and neuronal system. Finally, we discuss the known and potential mechanisms underlying the involvement of comorbidities, gender and age in development of COVID‐19. Consequently, we highlight the knowledge gaps and urgent research requirements to provide a quick roadmap for ongoing and needed COVID‐19 studies."

Telemedicine allows quantitative measuring of olfactory dysfunction in COVID‐19


"For the first time, quantitative psychophysical analyses of olfaction were performed over a full course of COVID-19 in this homogenous cohort of relatively young adults, while previous studies used self-ratings, only. It is well accepted that self-ratings largely underestimate olfactory dysfunction. Usually required face-to-face contact seems to cause this systematic error, while telemedicine consultations allows safe testing for patients and staff. The comprehensive impairment without nasal symptoms supports the suggestion of a neurotropic and neuro-invasive virus that is site-specific for the olfactory system using angiotensin-converting-enzyme-receptor-2 (ACE2) for intracellular invasion."

The role of peripheral blood eosinophil counts in COVID‐19 patients


"The majority of COVID‐19 patients (71.7%) had a decrease in circulating EOS counts, which was significantly more frequent than other types of pneumonia patients. EOS counts had good value for COVID‐19 prediction, even higher when combined with NLR. Patients with low EOS counts at admission were more likely to have fever, fatigue and shortness of breath, with more lesions in chest CT and radiographic aggravation, longer length of hospital stay and course of disease than those with normal EOS counts."

Eosinopenia is associated with greater severity in patients with coronavirus disease 2019


"Based on accumulating data, patients with severe COVID-19 show a trend towards eosinopenia, which raises the concern whether eosinopenia is associated with the disease severity. Eosinophil, initially identified as a key effector cell of allergy, has now been demonstrated to possess antiviral capacities and serve to amply immune response and thus dampen inflammation. It is currently not known whether COVID-19 patients with eosinopenia are also more likely to develop into critically illness. This updated analysis aimed to investigate the association between eosinopenia and COVID-19 severity."

COVID‐19 in a patient with severe asthma treated with Omalizumab


"ircumstantial evidence suggests that patients with allergic asthma might have a lower risk to develop severe forms of COVID‐19. In addition, the anti‐IgE antibody Omalizumab was shown to enhance anti‐viral immunity. We report a case of a 52‐year‐old man with severe allergic asthma treated with Omalizumab with no evidence of an asthma exacerbation, loss of asthma control or pneumonia during symptomatic COVID‐19 disease. We hypothesize that the underlying disease (allergic asthma) or the antibody used for treatment (Omalizumab), or both, might have exerted protective effects."

Clinical characteristics of 182 pediatric COVID‐19 patients with different severities and allergic status


"Pediatric COVID‐19 patients tended to have a mild clinical course. Patients with pneumonia had higher proportion of fever and cough and increased inflammatory biomarkers than those without pneumonia. There was no difference between allergic and non‐allergic COVID‐19 children in disease incidence, clinical features, laboratory and immunological findings. Allergy was not a risk factor for developing and severity of SARS‐CoV‐2 infection and hardly influenced the disease course of COVID‐19 in children."

Is asthma protective against COVID‐19?


"(...) there are no published reports of other type 2 conditions associated with severe COVID-19. Herein, we share some clues supporting the hypothesis that type 2 conditions do not represent a risk factor, despite the most morbidity occurring due to SARS-CoV-2 induced lung damage."

Low prevalence of bronchial asthma and chronic obstructive lung disease among intensive care unit patients with COVID‐19


"In an uncontrolled study, we could not rule out the contribution of COPD to the more severe outcomes of SARS-CoV-2 infection that was shown in the previous studies. However, patients with bronchial asthma do not seem to be at increased risk of SARS-CoV-2 induced ARDS. Our findings suggest that there is no need to change standard treatment for chronic respiratory diseases during pandemic of COVID-19. Additional studies are needed to prove this hypothesis."

COVID‐19 Clinical trials: quality matters more than quantity


"Hopefully, the efforts of clinical researchers in the fight against the SARS Cov‐2 will result into the identification of effective treatments. To make this possible, clinical research should be oriented by guidelines for more harmonized high‐quality studies and by a united commitment of the scientific community to share personal knowledge and data. Allergists and clinical immunologists should have a leading role in this unprecedent challenge."

Allergy and asthma in children and adolescents during the COVID outbreak: what we know and how we could prevent allergy and asthma flares?


"Coronavirus disease 2019 (COVID‐19) pandemic is affecting people at any age with a more severe course in patients with chronic diseases or comorbidities, males and elderly patients. The Center for Disease Control and Prevention (CDC) initially proposed that patients with chronic lung diseases, including moderate‐severe asthma, and allergy may have a higher risk of developing severe COVID‐19 than otherwise healthy people"

Managing ocular allergy in the time of COVID‐19


"This spring, the majority of allergic patients are confined to their homes due to COVID‐19 pandemic restrictions. In the following weeks, these restrictions will be reduced andpeople will be allowed to take walks, go jogging, and return to work.Spring is the time for ocular allergy (OA) to emerge with signs and symptoms consequent to increasing pollen counts. Even when wearing a mask, the eyes may remain unprotectedleading to an increase in ocular symptoms and patients seeking treatment forOA. However, access to routine consultation may remain problematic for many patients."

Asthma and COVID‐19: is asthma a risk factor for severe outcomes?


"My recommendations to people with asthma and those treating them are most importantly to optimize asthma control with standard therapies, but if asthma control is not optimal despite appropriate use of standard therapies, to have a low threshold for starting azithromycin prophylaxis (because of its innate antiviral (IFN-boosting) property, at this time of enormous threat from COVID-19."

Is global BCG vaccination‐induced trained immunity relevant to the progression of SARS‐CoV‐2 pandemic?


"Even though we are still in the midst of the coronavirus pandemic, the disproportionately smaller number of cases reported from disadvantaged/low income countries remains puzzling. We hypothesize that general BCG vaccination policies adopted by different countries might have impacted the transmission patterns and/or COVID-19 associated morbidity and mortality."

Is BCG vaccination effecting the spread and severity of COVID‐19?


"As allergists and immunologists, we are very familiar with the T helper (Th)1 and Th2 balance in addition to orchestral roles of T regulatory and other effector cells, so we have to consider the possible roles of childhood immunizations within the context of the current coronavirus disease 2019 (COVID-19) outbreak."

Intranasal corticosteroids in allergic rhinitis in COVID‐19 infected patients: An ARIA‐EAACI statement


"Some sources have suggested that “corticosteroids” should be avoided during the for SARS-CoV-2 epidemic. This advice is about the use of oral corticosteroids unless there is a clear indication for their use. Patients with asthma should not stop their prescribed inhaled corticosteroid controller medication (or prescribed oral corticosteroids). Stopping inhaled corticosteroids often leads to potentially dangerous worsening of asthma, and avoiding oral corticosteroids during severe asthma attacks may have serious consequences."
